Protection Setting of Voltage-Time Column Switch

With the continuous expansion of the distribution automation construction scale,it is necessary to plan the feeder automation protection setting scheme reasonably to improve the power supply reliability of the distribution network. Therefore,this paper explored the technical means and automatic configuration scheme of the voltage time type feeder automation column section switch,and analyzed the protection setting scheme and calculation method of the voltage time type column section switch by using the reclosing sequence diagram. The result of case analysis shows that the protection setting scheme of the voltage time type feeder automation column section switch proposed in this paper is reasonable and effective,which has important guiding significance for engineering application.
